Cracked is broken. Thats 11 broken rocker arms in five years and you have raced "a few" races a year. If that was two races a year, that would be ten races in five years. That's .9 broken rockers per race.
I remember one year Scott Pearson could only afford to race two national events. He won them both. True he races SS/JA but there are many Stock racers like yourself that can't afford to attend many races. Sure would suck if you broke a rocker in a final round! Even first round breakage would cost you a lot of money.

A few?

How many Division 2 races did you and Brenda skip this year Bill? We didn't make the tour this year, we'll be back next year.



We have never broken a rocker arm, not in 6 years, although this year was real short. We've broken one 7/16" rocker stud, the poly lock killed the entire engine, including the block. We have only run near 500 passes on one set of rockers, and maybe 300 passes on the other set. No, we ain't as fast as some, but we haven't lost too many heads up races, we've got 2-3 class wins, and we usually go a few rounds fairly often. It may not be a rocket, but it ain't a slug, either.

How about the shaft type rocker guys..................

Jesel or T&D......

Take your pick

No potential performance gain.......Give me a break

It's my understanding that the shaft type rockers are not legal for stock.

The better question is:

Why would you want a roller rocker that is shaftless?

[Greg Hill]

Stud mounted rockers are what I was told and that jessel or t&d rockers are not legal. I think you all know what i meant.

[Woodro Josey]

So now, does it have to be a certain mfg or is any mfg legal, for the stud mount rocker?

News flash !! Some engine's come with a shaft from the start ! Some Ford
FE and some GM and Dodge and the list goes on .

I was wondering when someone would finally point that out !
I'm a Chevy guy... pre 73 that is. No shafts there. However, to my knowledge, don't most Mopars of that earlier era, have shaft rockers ?
I'm sure it's safe to assume that the new rule will at least madate that the engine has to possess the original rocker configuration.
Does that mean that the shaft-rocker engines will have an advantage ?
perhaps a little
That's the way it is.
